333. Disassembly and Reassembly

3.1 General Precautions on Disassembly

When you disassemble and reassemble compo-nents, you must use extreme caution. The closeproximity of cables to moving parts makes properrouting a must. If components are removed, any cables disturbedby the procedure must be restored as close aspossible to their original positions. Before remov-ing any component from the machine, note thecable routing that will be affected.

Whenever servicing the machine, you

must perform as follows:

1. Check to verify that documents are not storedin memory.

2. Be sure to remove the print cartridge beforeyou disassemble parts.

3. Unplug the power cord.

4. Use a flat and clean surface.

5. Replace only with authorized components.

6. Do not force plastic-material components.

7. Make sure all components are in their properposition.

Releasing Plastic Latches

Many of the parts are held in place with plasticlatches. The latches break easily; release themcarefully. To remove such parts, press the hook end of thelatch away from the part to which it is latched.
